The block copolymer is selectively hydrogenated and has mono alkenyl arene end blocks and a controlled distribution block of a mono alkenyl arene and a conjugated diene midblock. The ester oil is a non-aromatic, ester compound such as soybean oil, coconut oil, and other like compounds.

FIELD OF THE INVENTION

The present invention relates to an oil gel composition, and moreparticularly to an oil gel composition including a controlleddistribution block copolymer and at least one non-aromatic ester oil.

BACKGROUND OF THE INVENTION

The preparation of block copolymers of mono alkenyl arenes andconjugated dienes is well known. One of the first patents on linear ABAblock copolymers made with styrene and butadiene is U.S. Pat. No.3,149,182. These polymers, in turn, could be hydrogenated to form morestable block copolymers, such as those described, for example, in U.S.Pat. No. 3,595,942 and U.S. Reexamination No. 27,145. Such polymers arebroadly termed ‘Styrenic Block Copolymers’ or SBC's.

SBC's have a long history of use as adhesives, sealants and gels. Arecent example of such a gel can be found, for example, in U.S. Pat. No.5,879,694. With the increased use of oil gels, the need for improvedproperties (expressed in terms of higher tensile strength and higherelongation) exist. Such gels may also be used, for example, as a waterproofing encapsulant/sealant for electronics and in wire and cableapplications.

An anionic block copolymer based on mono alkenyl arene end blocks and acontrolled distribution mid block of a mono alkenyl arene and aconjugated diene has been discovered and is described in copending andcommonly assigned U.S. patent application Ser. No.10/359,981, filed Feb.6, 2003 and entitled “NOVEL BLOCK COPOLYMERS AND METHOD FOR MAKINGSAME”. Methods for making such polymers are described in detail in theabove-mentioned patent application.

Copending and commonly assigned U.S. patent application Ser. No.10/359,462 filed Feb. 6, 2003 and Ser. No. 10/745,352 filed Dec. 22,2003, both entitled “GELS FROM CONTROLLED DISTRIBUTION BLOCK COPOLYMERS”describe gel compositions that include the anionic block copolymer ofthe '981 application and a mineral oil such as, for example, apetroleum-based white oil. Examples of such petroleum-based oils includeparaffinic oil and naphthenic oil. It is reported in the '462 and the'352 applications that such gel compositions have improved propertiesincluding, for example, a high softening point and melt viscosity, ascompared to gel compositions that include conventional hydrogenatedanionic block copolymers.

Although improved gel compositions are disclosed in the '462 and '352applications, those gel compositions use mineral oils that are notconsidered to be environmentally friendly. There is thus an interest ingelling natural product oils, such as soybean oil, because the naturalproduct oils are considered to be more environmentally friendly. Oneproblem with using natural product oils in the preparation of gelcompositions is that such oils are not always compatible with thepolymer it is being gelled with. For example, natural product oils aretoo polar to be used with most conventional anionic block copolymers.

It has now been surprisingly discovered by the present applicant thatthe anionic block copolymers of the '981 application are compatible withnatural product oils such as, for example, soybean oil and other likeester compounds, and that substantially clear blends, which do notexhibit any significant oil bleed can be formulated.

DETAILED DESCRIPTION OF THE INVENTION

As stated above, the present invention provides an oil gel compositionwhich includes, as essential components, at least one hydrogenatedanionic block copolymer (to be described in greater detail herein below)and an ester oil (also to be described in greater detail herein below)or a mixture of ester oils.

The oil gel compositions of the present invention are made usingconventional procedures well known in the art. Typically, the gelcompositions of the present invention are made by blending at least theester oil with a hydrogenated anionic block copolymer having thecontrolled distribution block. The blends can be made using anyconventional mixing apparatus and mixing can occur at room temperatureor at a temperature that is elevated from room temperature. For example,the mixing of the two essential components, together with other optionalcomponents (to be described in greater detail below), may be performedat a temperature from about 120° C. to about 175° C.

As stated above, one of the essential components of the inventive oilgel composition is a hydrogenated block copolymer containing monoalkenyl arene end blocks and a unique mid block of a mono alkenyl areneand a conjugated diene, such as described in the '981 applicationmentioned above. The entire contents of the '981 application,particularly the anionic polymerization method described therein, arethus incorporated herein by reference. Surprisingly, the combination of(1) a unique control for the monomer addition, and (2) the use ofdiethyl ether or other modifiers as a component of the solvent (which isreferred to as a “distribution agent”) results in a certaincharacteristic distribution of the two monomers (herein termed a“controlled distribution” polymerization, i.e., a polymerizationresulting in a “controlled distribution” structure), and also results inthe presence of certain mono alkenyl arene rich regions and certainconjugated diene rich regions in the polymer block.

For purposes hereof, “controlled distribution” is defined as a molecularstructure having the following attributes: (1) terminal regions adjacentto the mono alkenyl arene homopolymer (“A”) blocks that are rich in(i.e., having a greater than average amount of) conjugated diene units;(2) one or more regions not adjacent to the A blocks that are rich in(i.e., having a greater than average amount of) mono alkenyl areneunits; and (3) an overall structure having relatively low mono alkenylarene, e.g., styrene, blockiness. For the purposes hereof, “rich in” isdefined as greater than the average amount, preferably 5% greater thanthe average amount. This relatively low mono alkenyl arene blockinesscan be shown by either the presence of only a single glass transitiontemperature (Tg) intermediate between the Tg's of either monomer alone,when analyzed using differential scanning calorimetry (“DSC”) thermalmethods or via mechanical methods, or as shown via proton nuclearmagnetic resonance (“H-NMR”) methods. The potential for blockiness canalso be inferred from measurement of the UV-visible absorbance in awavelength range suitable for the detection of polystyryllithium endgroups during the polymerization of the B block. A sharp and substantialincrease in this value is indicative of a substantial increase inpolystyryllithium chain ends. In such a process, this will only occur ifthe conjugated diene concentration drops below the critical level tomaintain controlled distribution polymerization. Any mono alkylene arenemonomer, such as, for example, styrene, that is present at this pointwill add in a blocky fashion. The term “styrene blockiness”, as measuredby those skilled in the art using proton NMR, is defined to be theproportion of S (i.e., styrene) units in the polymer having two Snearest neighbors on the polymer chain. Although this discussion relatesto styrene blockiness, it is appreciated by those skilled in the artthat the same holds for any mono alkenyl arene monomer.

The styrene blockiness is determined after using H-1 NMR to measure twoexperimental quantities as follows: First, the total number of styreneunits (i.e., arbitrary instrument units which, when a ratio is taken,cancel out) is determined by integrating the total styrene aromaticsignal in the H-1 NMR spectrum from 7.5 to 6.2 ppm and dividing thisquantity by 5 to account for the 5 aromatic hydrogens on each styrenearomatic ring. Second, the blocky styrene units are determined byintegrating that portion of the aromatic signal in the H-1 NMR spectrumfrom the signal minimum between 6.88 and 6.80 to 6.2 ppm and dividingthis quantity by 2 to account for the 2 ortho hydrogens on each blockystyrene aromatic ring. The assignment of this signal to the two orthohydrogens on the rings of those styrene units which have two styrenenearest neighbors was reported in F. A. Bovey, High Resolution NMR ofMacromolecules (Academic Press, New York and London, 1972), Chapter 6.

The styrene blockiness is simply the percentage of blocky styrene tototal styrene units:Blocky %=100 times (Blocky Styrene Units/Total Styrene Units)

Expressed thus, Polymer-Bd-S—(S)_(n)—S-Bd-Polymer, where n is greaterthan zero is defined to be blocky styrene. For example, if n equals 8 inthe example above, then the blockiness index would be 80%. It ispreferred in the present invention that the blockiness index be lessthan about 40. For some polymers, having styrene contents of ten weightpercent to forty weight percent, it is preferred that the blockinessindex be less than about 10.

This controlled distribution structure is very important in managing thestrength and Tg of the resulting copolymer, because the controlleddistribution structure ensures that there is virtually no phaseseparation of the two monomers, i.e., in contrast with block copolymersin which the monomers actually remain as separate “microphases”, withdistinct Tg's, but are actually chemically bonded together. Thiscontrolled distribution structure assures that only one Tg is presentand that, therefore, the thermal performance of the resulting copolymeris predictable and, in fact, predeterminable. Furthermore, when acopolymer having such a controlled distribution structure is then usedas one block in a di-block, tri-block or multi-block copolymer, therelatively higher Tg made possible by means of the presence of anappropriately-constituted controlled distribution copolymer region willtend to improve flow and processability. Modification of certain otherproperties is also achievable.

In a preferred embodiment of the present invention, the subjectcontrolled distribution copolymer block has two distinct types ofregions—conjugated diene rich regions on the ends of the block and amono alkenyl arene rich region near the middle or center of the block.In particular, a mono alkenyl arene/conjugated diene controlleddistribution copolymer block is desired, wherein the proportion of monoalkenyl arene units increases gradually to a maximum near the middle orcenter of the block and then decreases gradually until the polymer blockis fully polymerized.

It is noted that the controlled distribution block of the anionic blockcopolymers employed in the present invention is not a random block inwhich the distribution of the monomer unit is statistical, nor is thecontrolled distribution block a tapered block in which there is agradual change in the composition of the polymer chain from one monomerunit to another.

Starting materials for preparing the controlled distribution copolymersemployed in the present invention include the initial monomers. Thealkenyl arene can be selected from styrene, alpha-methylstyrene,para-methylstyrene, vinyl toluene, vinylnaphthalene, and para-butylstyrene or mixtures thereof. Of these, styrene is most preferred and iscommercially available, and relatively inexpensive, from a variety ofmanufacturers. The conjugated dienes that can be used in preparing theanionic block copolymer employed in the present invention are1,3-butadiene and substituted butadienes, such as, for example,isoprene, piperylene, 2,3-dimethyl-1,3-butadiene, and1-phenyl-1,3-butadiene, or mixtures thereof. Of these, 1,3-butadiene ismost preferred. As used herein, “butadiene” refers specifically to“1,3-butadiene”.

As discussed above, the controlled distribution polymer block has dienerich region(s) adjacent to the A block and an arene rich region notadjacent to the A block, and typically near the center of the B block.Typically, the region adjacent to the A block comprises the first 15 to25% of the block and comprises the diene rich region(s), with theremainder considered to be arene rich. The term “diene rich” means thatthe region has a measurably higher ratio of diene to arene than thearene rich region. Another way to express this is the proportion of monoalkenyl arene units increases gradually along the polymer chain to amaximum near the middle or center of the block (assuming an ABAstructure is being described) and then decreases gradually until thepolymer block is fully polymerized. For the controlled distributionblock B, the weight percent of mono alkenyl arene is between about 10percent and about 75.

As used herein, “thermoplastic block copolymer” is defined as a blockcopolymer having at least a first block of a mono alkenyl arene, such asstyrene, and a second block of a controlled distribution copolymer ofdiene and mono alkenyl arene. The method to prepare this thermoplasticblock copolymer is via any of the methods generally known for blockpolymerizations. The present invention includes as an embodiment athermoplastic copolymer composition, which may be either a di-block,tri-block copolymer or multi-block composition. In the case of thedi-block copolymer composition, one block is the alkenyl arene-basedhomopolymer block and polymerized therewith is a second block of acontrolled distribution copolymer of diene and alkenyl arene. In thecase of the tri-block composition, it comprises, as end-blocks theglassy alkenyl arene-based homopolymer and as a mid-block the controlleddistribution copolymer of diene and alkenyl arene. Where a tri-blockcopolymer composition is prepared, the controlled distributiondiene/alkenyl arene copolymer can be herein designated as “B” and thealkenyl arene-based homopolymer designated as “A”.

The A-B-A, tri-block compositions can be made by either sequentialpolymerization or coupling. In the sequential solution polymerizationtechnique, the mono alkenyl arene is first introduced to produce therelatively hard aromatic block, followed by introduction of thecontrolled distribution diene/alkenyl arene mixture to form the midblock, and then followed by introduction of the mono alkenyl arene toform the terminal block. In addition to the linear, A-B-A configuration,the blocks can be structured to form a radial (branched) polymer,(A-B)_(n)X, or both types of structures can be combined in a mixture.Some A-B diblock polymer can be present, but preferably at least about30 weight percent of the block copolymer is A-B-A or radial (orotherwise branched so as to have 2 or more terminal resinous blocks permolecule) so as to impart strength.

It is also important to control the molecular weight of the variousblocks. For an AB diblock, desired block weights are 3,000 to about60,000 for the mono alkenyl arene A block, and 30,000 to about 300,000for the controlled distribution conjugated diene/mono alkenyl arene Bblock. Preferred ranges are 5,000 to 45,000 for the A block and 50,000to about 250,000 for the B block. For the triblock, which may be asequential ABA or coupled (AB)₂X block copolymer, the A blocks should be3,000 to about 60,000, preferably 5,000 to about 45,000, while the Bblock for the sequential block should be about 30,000 to about 300,000,and the B blocks (two) for the coupled polymer half that amount. Thetotal average molecular weight for the triblock copolymer should be fromabout 40,000 to about 400,000, and for the radial copolymer from about60,000 to about 600,000. These molecular weights are most accuratelydetermined by light scattering measurements, and are expressed as numberaverage molecular weights.

Another important aspect of the anionic block copolymer employed in thepresent invention is to control the microstructure or vinyl content ofthe conjugated diene in the controlled distribution copolymer block. Theterm “vinyl content” refers to a conjugated diene that is polymerizedvia 1,2-addition (in the case of butadiene—it would be 3,4-addition inthe case of isoprene). Although a pure “vinyl” group is formed only inthe case of 1,2-addition polymerization of 1,3-butadiene, the effects of3,4-addition polymerization of isoprene (and similar addition for otherconjugated dienes) on the final properties of the block copolymer willbe similar. The term “vinyl” refers to the presence of a pendant vinylgroup on the polymer chain. When referring to the use of butadiene asthe conjugated diene, it is preferred that about 20 to about 80 molpercent of the condensed butadiene units in the copolymer block have 1,2vinyl configuration as determined by proton NMR analysis, preferablyabout 30 to about 70 mol percent of the condensed butadiene units shouldhave 1,2-vinyl configuration. This is effectively controlled by varyingthe relative amount of the distribution agent. As will be appreciated,the distribution agent serves two purposes—it creates the controlleddistribution of the mono alkenyl arene and conjugated diene, and alsocontrols the microstructure of the conjugated diene. Suitable ratios ofdistribution agent to lithium are disclosed and taught in U.S. Pat.Reexamination No. 27,145, which disclosure is incorporated by reference.

Another feature of the thermoplastic elastomeric di-block and tri-blockpolymers of the anionic copolymer employed in the present invention,including one or more controlled distribution diene/alkenyl arenecopolymer blocks and one or more mono alkenyl arene blocks, is that theyhave at least two Tg's, the lower being the combined Tg of thecontrolled distribution copolymer block which is an intermediate of itsconstituent monomers' Tg's. Such Tg is preferably at least about −60°C., more preferably from about −40° C. to about +30° C., and mostpreferably from about −40° C. to about +10° C. The second Tg, that ofthe mono alkenyl arene “glassy” block, is preferably more than about 80°C., more preferably from about +80° C. to about +110° C. The presence ofthe two Tg's, illustrative of the microphase separation of the blocks,contributes to the notable elasticity and strength of the material in awide variety of applications, and its ease of processing and desirablemelt-flow characteristics.

In some embodiments of the present invention, a hydrogenated blockcopolymer that is a linear hydrogenated ABA styrene/butadiene blockcopolymer having a total molecular weight of about 80,000 to about200,000 is employed. In another embodiment of the present invention, itis preferred to use an anionic block polymer of the S-EB/S-S type. Thisformula indicates a polymer having a polystyrene block (S) on both endsof a hydrogenated polybutadiene (EB)/styrene (S) controlled distributionmidblock. One example of a preferred S-EB/S-S type polymer is onewherein the molecular weight of the various blocks is29,000-80,000/50,000-29,000, the % weight styrene is 57.5%, the % weightstyrene in the EB/S mid block is 39% and the 1,2/1,4-butadiene ratio is40/60. Another preferred anionic polymer of the S-EB/S-S type is onewherein the molecular weight of the various blocks is9,500-60,000/20,000-9,500, the % weight styrene is 39.5%, the % weightstyrene in the EB/S mid block is 25% and the 1,2/1,4-butadiene ratio is40/60. Of these preferred S-EB/S-S type polymers, the first onementioned above is most preferred.

The anionic block copolymer employed in the present invention isselectively hydrogenated. Hydrogenation can be carried out via any ofthe several hydrogenation or selective hydrogenation processes known inthe prior art. For example, such hydrogenation has been accomplishedusing methods such as those taught in, for example, U.S. Pat. Nos.3,494,942, 3,634,594, 3,670,054, 3,700,633 and Reexamination No. 27,145.Typically, hydrogenation is carried out under such conditions that atleast about 90 percent of the conjugated diene double bonds have beenreduced, and between zero and 10 percent of the arene double bonds havebeen reduced. Preferred ranges are at least about 95 percent of theconjugated diene double bonds reduced, and more preferably about 98percent of the conjugated diene double bonds are reduced. Alternatively,it is possible to hydrogenate the polymer such that aromaticunsaturation is also reduced beyond the 10 percent level mentionedabove. In that case, the double bonds of both the conjugated diene andarene may be reduced by 90 percent or more.

In an alternative, the block copolymer employed in the present inventionmay be functionalized in a number of ways. One way is by treatment withan unsaturated monomer having one or more functional groups or theirderivatives, such as carboxylic acid groups and their salts, anhydrides,esters, imide groups, amide groups, and acid chlorides. The preferredmonomers to be grafted onto the block copolymers are maleic anhydride,maleic acid, fumaric acid, and their derivatives. A further descriptionof fuctionalizing such block copolymers can be found in U.S. Pat. Nos.4,578,429 and 5,506,299. In another manner, the selectively hydrogenatedblock copolymer employed in the present invention may be functionalizedby grafting silicon or boron-containing compounds to the polymer astaught, for example, in U.S. Pat. No. 4,882,384. In still anothermanner, the block copolymer of the present invention may be contactedwith an alkoxy-silane compound to form silane-modified block copolymer.In yet another manner, the block copolymer of the present invention maybe functionalized by reacting at least one ethylene oxide molecule tothe polymer as taught in U.S. Pat. No. 4,898,914, or by reacting thepolymer with carbon dioxide as taught in U.S. Pat. No. 4,970,265. Stillfurther, the block copolymers of the present invention may be metallatedas taught in U.S. Pat. Nos. 5,206,300 and 5,276,101, wherein the polymeris contacted with an alkali metal alkyl, such as a lithium alkyl. Andstill further, the block copolymers of the present invention may befunctionalized by grafting sulfonic groups to the polymer as taught inU.S. Pat. No. 5,516,831.

The other essential component of the inventive oil gel composition is anester oil. The term “ester oil” is used herein to describe anynon-aromatic ester compound including monoesters, diesters or triesters.An ester as used herein is a compound that includes at least onecarboxylate group: R—COO—, where R is hydrogen or a hydrocarbyl radical.The term “hydrocarbyl” is used herein to denote aliphatic or cyclicgroups that include elements of C and H having from 1 to about 30 carbonatoms. Aliphatic groups include, for example, alkyl groups, alkenylgroups or alkynyl groups. The hydrocarbyl groups can be substituted withany group as desired, except for, an aromatic group.

Suitable esters that can be employed in the present invention includethose of the following formulas:

where n has any value from 1 to about 8, and R₁ and R₂ are the same ordifferent and are hydrogen or a hydrocarbyl (including substitutedhydrocarbyls). It is noted that a suitable group for R₂ depends on thevalue of n. It is noted that the sugar esters of fatty acids, such assucrose esters of fatty acids, are also contemplated herein.

In one embodiment of the present invention, n is 1, and the ester hasthe formula R₁C(O)OR₂ where R₁ is a C₁₀-C₂₀, preferably a C₁₅-C₁₈, andeven more preferably a C₁₇, alkyl, and R₂ is a lower alkyl radicalcontaining from 1 to 10, preferably 8 carbon atoms.

Another class of suitable esters that may be employed in the presentinvention is represented by the following formula:

where R₁ is defined above and R₃ includes alkylene or substitutedalkylene.

Still another class of suitable esters that may be employed in thepresent invention is represented by the following formula:

where R₄, R₅, and R₆ individually include alkylene or substitutedalkylene; and R₇, R₈, and R₉ individually include hydrogen or ahydrocarbyl.

Specifically, the anionic block copolymers employed in thisexample included: Copolymer 1 (a copolymer within the presentinvention), Copolymer 2 (another copolymer within the scope of thepresent invention) and Copolymer 3 (a copolymer outside of the presentinvention). Copolymer 1 was a S-EB/S-S polymer in which each S end blockhad a MW of about 29,000 and the EB/S midblock had a MW of80,000/50,000. The styrene content of Copolymer 1 was 57.5% by weightand the styrene content of the EB/S midblock was 39% by weight.Copolymer 2 was a S-EB/S-S polymer in which each S end block had a MW ofabout 9,500 and the EB/S midblock had a MW of 60,000/20,000. The styrenecontent of Copolymer 2 was about 39.5% by weight and the styrene contentin the EB/S midblock was about 25% by weight. Copolymers 1 and 2 had a1,2/1,4-Bd ratio of about 40/60. Copolymer 3 was a S-EB-S type polymerhaving the following block MW 10,000-80,000-10,000; % weight S of 20.5and a 1,2/1,4-Bd ratio of 65/35.

In this example, Cargill® Soybean Oil (a triglyceride of C₁₈ acids),Erucicial® EG-20 (an eicosyl erucate ester supplied by Lambert Tech),Finester® EH-25 (a C₁₂₋₁₅ alkyl octanoate supplied by Fintex), Finsolv®TN (a C₁₂₋₁₅ alkyl benzoate supplied by Fintex) and Neo Heliopan AV® (anoctyl methoxy cinnamate supplied by Liberty Natural) were used. Thefirst three ester oils fall within the scope of the present invention,while the last two ester oils are aromatic oils that fall outside thescope of the present invention.

Copolymer 1 was blended into the oils at 7.5% by weight copolymer andCopolymers 2 and 3 were blended into the oils at 15% by weightcopolymer. 0.1% by weight Irganox® 1010 (a hindered phenolic antioxidantsupplied by Ciba) was also included in each blend. The polymers weremixed into the oils by blending for about 1 to 1.5 hour at 130°-170° C.with a Silverson® mixer. Table 1 below shows the various oil gels thatwere prepared and provides characterization of the resultant oil gels.TABLE 1 Gels of Ester Oils Gel 1: 7.5% Gel 2: 15.0% Gel 3: 15.0% byweight by weight by weight Copolymer 1 + Copolymer 2 + Copolymer 3 +92.4% by 84.9% by 84.9% by weight oil weight oil weight oil Soybean OilYellow, slight Yellow, slight Yellow, opaque, haze, solid haze, self-solid rubbery rubbery gel, levels gel, some free very slight oil oilbleed after 1 month Erucical ® Yellow, clear, Yellow, slight Yellow,clear, EG-20 solid rubbery haze, solid solid rubbery gel, no freerubbery gel, gel, no free oil no free oil oil Finester ® Very slightBluish haze, Bluish haze, EH-25 haze, color- colorless, colorless, less,solid thickened but thickened but rubbery gel, low viscosity lowviscosity no free oil Finsolv ® Colorless, Colorless, Colorless, very TNvery clear, slight haze, slight haze, low viscosity thickened butthickened but low viscosity low viscosity Neo Heliopan Thickened, Veryslight Low viscosity, AV ® slight thixo- bluish haze, slight bluishtropy, clear, colorless, haze, colorless colorless, thixotropic gel,very slight no elasticity bluish haze

The results provided in Table 1 illustrate that in soybean oil, bothCopolymer 1 and 2 gave fairly clear blends. Copolymer 1 gave a nicerubbery gel, although it was quite soft. Copolymer 2 thickened soybeanoil, but did not gel it at 15% weight. Copolymer 3 was incompatible withsoybean oil; it made an opaque gel and the polymer did not hold oil. InErucical® EG-20, all three polymers gave a nice, clear, rubbery gel withno oil bleed. In Finester® EH-25, all three polymers gave a nearly clearblend, but only Copolymer 1 gelled that oil. In the two aromatic esteroils, all three polymers were soluble and gave clear blends, but none ofthem gave a rubbery gel in the oils.

EXAMPLE 2

In this example, Copolymer 1 was compared with Copolymer 4 (an S-EB-Stype polymer having block MW of 29,000-130,000-29,000, a styrene %weight of 33 and a 1,2/1,4-Bd ratio of 40/60). The various estersemployed in Example 1 were used in this example as well. Table 2includes the formulations and results with Copolymer 1, while Table 3includes the formulations and results for Copolymer 4.

Note that the copolymers behave similarly in all oils except for soybeanoil in which Copolymer 4 was incompatible.

EXAMPLE 3

In this example, more blends were made with Copolymer 1 to betterunderstand its capability. Table 4 presents formulations and results forCopolymer 1 in non-aromatic ester oils of the present invention. Table 5shows blends of Copolymer 1 with aromatic oils for comparative purposes.

As shown in Table 4, in soybean oil, Copolymer 1 at 9% by weight stillshowed a very slight oil bleed. At 12% by weight, no oil bleed wasfound. Blends at up to 15% by weight of Copolymer 1 could be made, butit is likely that higher concentrations would be too viscous to mix withthe Silverson® mixer. The gels in soybean oil become clearer withincreasing Copolymer 1 content.

The results in Table 4 show that Copolymer 1 had excellent compatibilitywith Erucical® EG-20. The blends were optically clear and showed no oilbleed, even at 7.5% by weight. These blends gave the highest softeningpoints, but also the highest melt viscosity.

The results in Table 4 show that Copolymer 1 also had excellentcompatibility with Finester® EH-25. These blends showed good clarity, nooil bleed and they were colorless. These blends gave much lowersoftening points than the blends with soybean oil and Erucical® EG-20.Softening points remained fairly low until the Copolymer 1 concentrationreached about 20% by weight. Fortunately, blends in Finester® EH-25 hadrelatively low viscosity so blends can be made with the Silverson® mixerat up to 25% by weight of Copolymer 1. Since gel hardness is directlyrelated to polymer content, this low viscosity allowed gels to be madewith Finester® EH-25 that have relatively high hardness.

The results in Table 5 show that none of the blends made with thearomatic oils gelled. Blends with Finsolv® TN at up to 20% by weight ofCopolymer 1 were thick but had almost no thixotropy or elasticity.

EXAMPLE 4

In this example, an oil gel composition comprising coconut oil andCopolymer 1 was prepared as outlined in Example 1 above. A comparison isshown with Copolymer 4. Stirring was performed at 160°-170° C. Thecoconut oil was 76° Edible Coconut Oil from Alnoroil Company, ValleyStream, N.Y. The following formulations were prepared and exhibited thefollowing properties: TABLE 6 Oil Gel Compositions with Coconut OilComposition, % by weight EE FF GG HH II Coconut Oil 92.4 90.9 87.9 84.992.4 Copolymer 1 7.5 9 12 15 Copolymer 4 7.5 Irganox ® 0.1 0.1 0.1 0.10.1 101 R&B 67 69 72 87 Softening Point, ° C.

When freshly made, Gels EE-HH were clear, rubbery gels at roomtemperature. After a few days, the coconut oil crystallized and the gelsbecame opaque. When freshly made, Gel II was rubbery, but it was opaqueand bled oil badly at room temperature, showing that the conventionalS-EB-S polymer is incompatible with coconut oil.
